Core Viewpoint - The article discusses the unusually long and wet rainy season in North China, highlighting its early onset and significant rainfall, which are attributed to various climatic factors and global warming effects [1][2][3]. Group 1: Rainy Season Characteristics - The rainy season in North China began on July 5, 2025, which is 13 days earlier than the average start date of July 18 [2]. - As of August 21, the average rainfall in the North China monitoring area reached 315.5 mm, which is 131% higher than the normal value of 136.6 mm [2]. Group 2: Contributing Factors - The increased rainfall is linked to several factors, including abnormal sea temperatures in the equatorial Pacific, a strong and shifted subtropical high-pressure system, typhoon activity, and geographical influences [3][4]. - The subtropical high-pressure system has been notably strong and positioned further north than usual, facilitating the transport of warm, moist air to northern China [3]. Group 3: Geographical Influence - The geographical features of the Beijing-Tianjin-Hebei region, including the Taihang and Yan mountains, enhance precipitation through orographic lift, which promotes condensation of moisture [4]. - The combination of topographical effects and weather systems significantly increases rainfall efficiency in the region [4].

Core Viewpoint - The northern regions of China, particularly North China, are experiencing an unusually prolonged rainy season, with significant rainfall exceeding historical averages, attributed to various climatic factors [2][3][4]. Summary by Sections Rainfall Patterns - The rainy season in North China began on July 5, 2023, which is 13 days earlier than the average, marking the earliest start since 1961 [2]. - As of August 25, 2023, the cumulative rainfall in the monitoring area of North China was 131% higher than the average [2]. Climatic Influences - The excessive rainfall is linked to abnormal sea temperatures in the equatorial Pacific, a strong and shifted subtropical high-pressure system, typhoon activity, and geographical factors [3]. - The subtropical high-pressure system has been notably strong and has shifted northward, allowing for continuous moisture transport from the ocean to northern regions [3]. Weather Systems and Topography - The influence of Typhoon "Zhu Jie Cao" has contributed additional moisture to North China, enhancing rainfall [4]. - The topographical features, such as the Taihang and Yanshan mountains, have caused forced uplift of warm, moist air, leading to increased precipitation through condensation and convection [4]. Climate Change Context - The record-breaking rainy season is seen as a localized manifestation of climate change, highlighting the need for improved climate adaptation and response capabilities to handle extreme weather events [4].
